Hi,
I may not understand your question. I think that you may need to clarify the differences between Program and Project.
As you know, Program is different from Project. For example, you cannot staff a program.
check below manual for more details.
Manage Multiple Child Investments in Parent Programs - CA PPM - 15.4.1 - CA Technologies Documentation
But you can add any projects as Subprojects into Program.
After that, you will view staff who is added in Subproject on Program->Team tab->Staff page.
This page is similar with Project->Team tab->Staff page, so you will see Actuals, ETC,... for each staff.
